That is a question the folks at ESPN.com tackled this week. The criteria were size, in-game antics and crowd volume.

Alabama earned the No. 2 ranking.

"If you've ever wanted to hear "Roll Tide" loudly chanted ad nauseam in your face, just take a trip to Bryant-Denny Stadium. You might as well stick around for 'Rammer Jammer' when the students let you know that their team 'just beat the hell outta you.'"

Auburn checks in at No. 5.

"All that blue-(navy)-and-orange movement from the students, who don't know how to stay quiet during games, will leave you dizzy if you're sporting the wrong colors. It's a section that arrives early and will drown you in its cheers for four quarters."
